# Protokol Inligting
|
|
|
|
**BACnet** is 'n **kommunikasieprotokol** vir Gebou Automatisering en Beheer (BAC) netwerke wat die **ASHRAE**, **ANSI**, en **ISO 16484-5 standaard** protokol benut. Dit fasiliteer kommunikasie tussen gebou automatisering en beheerstelsels, wat toepassings soos HVAC-beheer, beligtingbeheer, toegangbeheer, en branddetectiestelsels in staat stel om inligting uit te ruil. BACnet verseker interoperabiliteit en laat gekomputeriseerde gebou automatisering toestelle toe om te kommunikeer, ongeag die spesifieke dienste wat hulle bied.

# Opname
|
|
|
|
## Handmatig
|
|
```bash
|
|
pip3 install BAC0
|
|
pip3 install netifaces
|
|
|
|
import BAC0
|
|
import time
|
|
|
|
myIP = '<Your IP>/<MASK>' #You need to be on the same subnet as the bacnet device. Example: '192.168.1.4/24'
|
|
bacnet = BAC0.connect(ip=myIP)
|
|
bacnet.whois() #Broadcast request of bacnet devices
|
|
time.sleep(5) #Wait for devices to respond
|
|
for i, (deviceId, companyId, devIp, numDeviceId) in enumerate(bacnet.devices):
|
|
print(f"-------- Device #{numDeviceId} --------")
|
|
print(f"Device: {deviceId}")
|
|
print(f"IP: {devIp}")
|
|
print(f"Company: {companyId}")
|
|
readDevice = bacnet.readMultiple(f"{devIp} device {numDeviceId} all")
|
|
print(f"Model Name: {readDevice[11]}")
|
|
print(f"Version: {readDevice[2]}")
|
|
# print(readDevice) #List all available info about the device
|
|
```
|
|
## Outomaties
|
|
```bash
|
|
nmap --script bacnet-info --script-args full=yes -sU -n -sV -p 47808 <IP>
|
|
```
|
|
Hierdie skrip probeer nie om 'n BACnet-netwerk as 'n buitelandse toestel aan te sluit nie, dit stuur eenvoudig BACnet versoeke direk na 'n IP-adresseerbare toestel.
